Chris Hemsworth asks wife for acting advice

Chris Hemsworth relies on Elsa Pataky for acting advice.

The 'In the Heart of the Sea' star admits he really values his Spanish actress wife's opinion and they always swap tips when it comes to work.

He said: "It's when [Elsa] forgets she's watching me on the screen that I know I've succeeded. Someone who knows you better than anyone is able to be swept away in an illusion? That's always a nice trick."

The Australian heartthrob's three-year-old daughter India is slowly becoming aware of his fame.

The star, who also has twin boys Sasha and Tristan, 19 months, with Elsa, said: "Once her friend had on a Spider-Man costume, so she put on a Thor costume.

"Of course she wouldn't take it off. Thankfully there weren't any paparazzi - you can imagine the headline - 'Forces Child to Wear Thor Costume.' "

Hemsworth recently decided to star in a number of comedies, including the upcoming 'Ghostbusters' film.

But he admitted to US' Glamour magazine: "The thought of doing comedy always scared the hell out of me, but I've never had so much fun as on the set of 'Ghostbusters'.

"With Kristen Wiig and Melissa McCarthy, I was either laughing all the time or just trying to keep it together. You have to improv - completely roll the dice and take a risk. The result can be fantastic."
